Coded Multi-tone Transmission in a DHA FH OFDMA system employing order statistics
P. 36–41.
In what follows a modified version of a coded DHA FH OFDMA communication system that combines multi-tone transmission, reception based on order statistics and concatenated coding is proposed. It is demonstrated that the proposed approach outperforms conventional (single-tone) coded DHA FH OFDMA while having lower decoding complexity.

Introduction: In many communication systems under construction and those to be created power control and channel estimation techniques developed for the previous generation communication systems fail to provide desired precision. One way to solve this problem is to use order-statistics-based reception techniques that do not need channel estimation or power control. To ensure the desired ...

The prominence of the Euler allocation rule (EAR) is rooted in the fact that it is the only return on risk-adjusted capital (RORAC) compatible capital allocation rule. When the total regulatory capital is set using the value-at-risk (VaR), the EAR becomes – using a statistical term – the quantile-regression (QR) function. Although the cumulative QR ...

We derive consistency, asymptotic normality, and standard error estimation for the tail conditional allocation, also known as the marginal expected shortfall, under minimal conditions and thus geared toward widest applicability. These advances have become possible due to a newly developed technique that hinges on compound sums of concomitants. An insurance inspired numerical study has been designed to illustrate the ...

Background, or systematic, risks are integral parts of many systems and models in insurance and finance. These risks can, for example, be economic in nature, or they can carry more technical connotations, such as errors or intrusions, which could be intentional or unintentional. A most natural question arises from the practical point of view: is ...

When dealing with control systems, it is useful and even necessary to assess the performance of underlying transfer functions. The functions may or may not be linear, may or may not be monotonic. They may have structural breaks and other aberrations that require monitoring and quantification to aid decision making. The present paper develops such ...

A coded DHA FH OFDMA system that employs non-coherent demodulation is considered. A coded modulation construction for this system and a novel low complexity detection algorithm that outperforms the previously proposed detection algorithms for the same rates are proposed. ...

Abstract Two families of scale-free exponentiality tests based on the recent characterization of exponentiality by Arnold and Villasenor are proposed. The test statistics are constructed using suitable functionals of U-empirical distribution functions. The family of integral statistics can be reduced to V- or U-statistics with relatively simple non-degenerate kernels. They are asymptotically normal and have ...
